Cut noise and vibration
Hear the Aquadrive Difference!
Much of the noise and vibration on a boat comes
from the engine, propeller, and propeller shaft. In a traditional
configuration, engine mounts must be extremely firm and rigid
to handle the load of the propeller shaft pushing against
Unfortunately, tight mounts do very little to
absorb noise and vibration. In fact, they broadcast nearly
all of the engine vibration right into the hull. Sandström
found that when the hull itself takes the load of the shaft,
the engine no longer needs hard mounts. He installed softer
mounts that absorbed nearly all of the engine vibration. It's
like mounting the engine on shock absorbers.
How quiet are boats with Aquadrive? As much
as 50 percent quieter - or quiet enough that the FBI and U.S.
Navy both use Aquadrive in vessels that require stealth and
speed (and increased reliability).
